1. Do you consider that microservices is fundamental to the Java Ecosystem?

In most projects we built “microservices” for several years without knowing the term. Microservices are not fundamental, they are rather natural fit to Java EE.

2. Do you believe that there is a delay in the adoption of microservices?No. My clients are perfectly happy with Java EE 7 full profile. It is surprisingly lean.However, monitoring could be even more standardized (beyond JSR-77) and exposed via stock JAX-RS.

Monitoring and other non-functional requirements are not the part of the microprofile.io, but this is just the start.

3. Why does this alliance arise prior to a JCP specification?Do you mean microprofile.io? It is just a pragmatic way to involve community. The goal is to standardize whatever possible with JCP. But we should involve the community first.

4.Will major changes in the use of microservices affect the develop meant of business applications?All project driven by actual requirements and not by esoteric architectures should look already surprisingly microservices compliant.5- Was us your opinion about Java EE Guardians and MicroProfile.io?I did not created Java EE Guardians (JEG). Because of lack of time I’m watching “from outside” what they are doing. IMO The JEG try to explain Oracle that Java EE is important for business.
